CRESSIDA (MOON)

:''There is also an asteroid called 548 Kressida.''

'Cressida' ''(kres'-ə-də,'' ) is an inner satellite of Uranus. It was discovered from the images taken by ''Voyager 2'' on 1986-01-09, and was given the temporary designation 'S/1986 U 3'.^[3] It was named after the Trojan daughter of Calchas, a tragic heroine who appears in William Shakespeare's play ''Troilus and Cressida'' (as well as in tales by Geoffrey Chaucer and others). It is also designated 'Uranus IX'.^[4]
Cressida belongs to Portia Group of satellites, which also includes Bianca, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita. These satellites have similar orbits and photometric properties. Unfortunately, other than its orbit, radius of 41 km and geometric albedo of 0.08 virtually nothing is known about it.
At the Voyager 2 images Cressida appears as an elongated object, the major axis pointing towards Uranus. The ratio of axises of the Cressida's prolate spheroid is 0.8 ± 0.3. Its surface is grey in color.
